I know this is somehow a common issue, however none of the solutions I found worked for me.
I have a macbook pro 15" late 2016 with high sierra. I have my laptop connected to external displays most of the time. Suddenly yesterday when I arrived at home I found that the main display was black, while laptop is running (I can ssh into it, or play with the touch bar...)
I tried every thing I found out there:
- reboot
- reset SMC
- reset non-volatile RAM
- I have done all the items above with both external displays connected and without any peripheral connected (just power).
Since this could be caused by a third party app I will list below the ones that have something to do with displays:
- Disable Monitor (this could be the issue, however I have not used this app during the last 2 months and it was not even installed...).
- Spectacle
- flux
The display does not seem to be detected by the graphical card, if I go to about this mac -> hardware -> Displays only my external displays are showing there.
Edit
I just noted that the apps that were using Touch ID don't ask for it anymore. Could it be because of the SMC/NVRAM reset?
To fix I had to add the fingerprint again
OS update
I updated mac osx to 10.13.4 just right now and nothing changed...
What else can I do ?
